{"product_id":"radiator-cap-193098","title":"Radiator Cap for Defender (1986 – 2006) Except TD5 – RTC3610","description":"\u003cp\u003eThe radiator cap for the Land Rover Defender is a pressure-relief component that maintains the correct operating pressure within the cooling system, raising the coolant's boiling point and allowing controlled venting to the expansion tank. A faulty or incorrect cap can result in coolant loss, overheating, or collapsed coolant hoses due to improper vacuum relief on cool-down. Using the correct rated cap is essential to maintaining system integrity across the range of petrol and diesel engines fitted to the Defender.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned to maintain the specified cooling system pressure for Defender petrol and non-TD5 diesel engines\u003c\/li\u003e\n\u003cli\u003eIncludes both pressure and vacuum relief valves to manage coolant flow to and from the expansion tank\u003c\/li\u003e\n\u003cli\u003eMatches original Land Rover OEM specification for the applicable Defender variants\u003c\/li\u003e\n\u003cli\u003eInspect the expansion tank and radiator filler neck sealing surface for corrosion or damage before fitting; replace as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Land Rover Defender from 1986 to 2006, covering all engines except the TD5 diesel variant.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
